To all whom it may concern:

Be it known that 'l, TALBOT C. DEXTER, a citizen of the United S ates, and a resident of Pearl River, in the county of Rockland and State of New York, have invented certain new and useful I iiprovements in haper- Feeding Machines, of which the following is a specification.

My present application is a division of my original :1 iplication Serial No. 442,114, filed July (3th, -908, for improvements in paper ne confeeding machines. HG/CUOII' of the lazy tongs with the under My present invention comprises an im- 'eed rollers and delivery transfer i were of proved tori n of mechanism for accurately the machine. F is a detail FJl-EW of adjusting the feeding and controlling depart of the same. 1g. 7 is a detail plan vices transversely of a paper feeding 111 view of a central set of under feed rollers, chine, the invention being not necessarily and Fig.8 is a detail elevation of one of the limited to a combing feeding machine, but central adjusting bracket n. 9 is n being applicable to various'forms of'sheet diagrammatic plan view ill strating the arieeding machines. lhis mechanism for adrangement of feeding devices upon opposite justiug the feeding and controllingdevices sides of the machine. of the feeding machine, includes a plurality of transversely arranged adjusting screws Paper feeding machines oi e type shown in my original application Serial No. 442,114,

engaging some of the parts which are to be above referred to, to which my present iniadjusted, and one or more series (preferably two) of lazy tongs connected with other provements have been applied, include two parts of the feeding devices for causing distinct sheet feeding and separating mechanisms, namely, first the means for gradu; them to be correspondingly adjusted to suit the adjusted positions of the main elements of the feeding mechanism. This adjustine mechanism is important not only because of the facility with which the operating ce vices of the machine may be accurately set to meet tl requirements of s particular ob, but also because of the eiliciency of the unachanism in holding the parts in the adjusted position. without danger of disari'zzngemcut during; the operation of the ma chine. The use of this adjusting mechanism also avoids the necessit of employing numerous small set screws for adjustably holding parts such as the under feed wheels in posit-ion, which screws are diilicult to get at for adjusting the parts, and are also very objectionable because of their liability to become loose and fall out into the machine with the possibility of seriously injuring some of the parts.

In order that my invention may be fully understood, I will first describe the some with reference to the accompanying drewings, and afterward: point out the novelty more particularly in the annexed claims.

in said drawings Figure l is a detail side elevation of part of a paper 'feedin inacl showing particularly th adjusting mechanism for the feeding devices. Fig. 2 is s detail plan view or part of the said adjusting inechai'iism. 3 is :1 detail rear elevation of the same. one. are detail plan views of the same lllQSlle sin showing different adjusted pos ions or the parts. Fig. 6 is an enlarged vertical logitudinal sectional view showing particularly t sheets by passing them from s supply table to a feed table, and presenting them in reversed position upon the feed table; and second, atinal separating and feeding niecl anism which successively detaches single sheets from the fanned out bank or pile and passes the individual sheets to delivery mechanism, which forwards the sheets to the machine which is to operate upon them;

With reference to means for eil'ectin'g the lateral adjustment of the sheet separating devices and controlling and delivery devices in a feeding machine of the type under discussion, it will be borne in vmind that in machines of this general type, and particularly in those machines which have been designed by me, the sheet separating and feeding devices are mounted upon auxiliary frames or saddles hung within the main frame upon transverse tie bars so that in the auxiliary frames or saddles are moved leterally upontheir supporting hers. This scljustment usuelly been eccornp shed by hand, theirimes or saddles hein'gheld ally forwarding and fanning out a bank of v adjustment of these feeding devices these i the desired adjusted position by set screws. or bolts. In addition to the main separating and feeding devices, the sheet delivery drop rollers and cotiperating under feed rollers, have also had to be adjusted laterally to suit the machine to the requirements of sheets of different sizes. These delivery devices have also in the past usually been adjusted by hand and held in adjusted position by set screws. It will also be observed that in machines of this type it is usual to provide two sets of separating and feeding devices to operate upon large sheets at opposite sides of a central line, so that it becomes necessary at times to adjust two sets of devices with relation to the central line or middle of the pile which is to be fed.

The improvements of my present invention relate to means for conveniently and accurately adjusting and securing the various operative parts of a feeding machine trans versely of the machine, which adjusting means are also valuable as affording a safe means for holding the parts in the desired adjusted position. I have thought it unnecessary to specifically illustrate all the details of a feeding ma chine of the type under discussion, but would refer to my application Serial No.

436,637, filed June 4th, 1908, as showing a,"

good example of this type of machine for, which my present improvements have been particularly designed.

In the accompanying drawings 79 is one of a pair of auxiliary frame pieces or saddles which support the main operative parts of the feeding machine, including the sheet combing and feeding Wheels and the sheet actuated tripping devices. Two of these frame pieces or saddles 79 carrying duplicate parts are arranged in my'machine as shown in Fig. 9 of the drawings. These parts are specifically shown and described in my above named application Serial No. d36,637, and the frame pieces and parts of the feeding devices so far as shown in the drawings in my present case, correspond with the same parts in said application.

S is the feed table, 40 the combing wheels, 41. short shafts, 42 rockarms in which shafts 41 are journaled, 86 a latch tripping arm, the sheet tripping finger, and the rod connecting arm 86 and finger 100.

Journaled in each of the main side frames of the feeding machine adjacent to the top, are the two laterally extending. adjusting screws and 136. Each of these screws 135, 136 extends inwardly and, passes through a threaded opening in one of the auxiliary frame pieces or saddles 79, so that when the screws are rotated the engaged auxiliary frame or saddle 79 will be moved transversely of the machine to one side or the other, depending .upon the direction in which the screws are rotating. It will, of

course, be understood that the screws projecting from one of the main side frames 78 engage the auxiliary frame or saddle nearest that side frame, and the same is true of the adjusting screws which are jonrnaled purpose of adjusting the under feed rollers 7 and transfer delivery lingers, in the manner presently to be explained. It will be understood that there are two screw shafts 137, one projectinginwardly from each of the main side frames of the machine.

' At each side of the machine, just inside of the main side frame 78, the screw shafts 135, 136 and 137 have keyed to-them small sprocket wheels 140, 141 and 142, and journaled on a stud 144 on the inner face of each of the main side frames 78 in a fourth sprocket wheel 143. An endless sprocket chain 145 passes-around and engages each so), of sprocket wheels 1442, 141,142 and 143, so,,as to cause all the screw shafts 135, 136 and-137 at om side of the ma chine to rotate n,1'inisoi i. Secured to the outer end of each "screw shaft 135, is a. hand crank 138, by the rotation of which all of the screws can be operated in 'either direction for ad usting theo erative parts of the machine either .inwar Iy outwardly.

as explained above, two of the adjusting screws at each side of the machine engage one of the auxiliary frames or saddles for adjusting said frames or saddles and the parts carried thereby. The third adjusting screw 137 of each set is for the purpose of correspondingly adjusting the under feed rollers and transfer fingers of the sheet delivery mechanism in the manner which I will now explain.

is the constantly driven shaft of the delivery mechanism. This shaft is suitably journaled in the side frames of the machine and suitable intermediate brackets (not shown) and is driven by gearing from the main drivmg shaft of the machine in a manner well understood. This constantly driven shaft 150 carries a plurality of un-' der feed rollers arranged in two adjustable series upon opposite sides of the central line of the machine, said feed rollers being splined to the shaft so as to rotate therewith, but permit their free adjustment transversely of the machine. Each adjustable scries of under feed rollers is of the same constructimi and arrangement both as to their moimting and method of adjustment, so that a specific explanation of one series will he understood to apply equally, to the other series.

As shown particularly in Figs. 1} and 5d which figures illustrate a complete series? extending one half the width of the feedingj se ne;

machine, it will be observed that a double or annularly flanged feed roller (fixed as to lateral adjustment by means presently to he explained), is arranged at the inner end of the series of feed rollers at one ,side of-the machine, said feed roller 155 being splined to the constantly rotating shaft 150. .t will also be observed that arranged between the feed roller 155 and the side frame of the machine, are similar double or annularly grooved feed rollers 156, and an elongated plural faced annularly grooved feed roller 157, said elongated plural faced roller being arranged upon the shaft 150 between two sets of the rollers 156, there beinglby preference three of the rollers 156 on either side of theelongated rpller 157. This elongated roller 157 is best shown in Fig. 14 of the drawin s, from which it will be observed that t ere are two central milled wheels 157, and two plain faced double or annularly grooved wheels 157 and 157, all

of said wheels constituting the elongatedroller 157, and being integral with or rigidly secured to a common elongated hub or sleeve 157 which is splined to the constantly rotating shaft 150 by spline 158 as shown particularly in 13 of the drawings. The purpose of mi ling the portions 157 of the elongated under feed roller is for cotiper'ation with the ordinary delivery drop rollers which operate in peripheral contact there.

with. 1 have not shown in my present application the arrangement of drop rollers, since they may be mounted and operated in any suitable manner well understood n the art, such for instance as illustrated 1n my above named application Serial No. 436,637.

160 is the delivery drum around which the shat conveying tapes operate for conveying the delivered sheets to the machine arrangedto receive them.

161 represents the sheet transfer fingers which lead from the delivery under feed rollers 156 157 to the delivery drum 160, in a manner well understood. The preferred mounting of these transfer fingers 161 will be hereinafter explained.

The rotating under feed roller 155 is held in its position against displacement laterally of themachine by means of a bracket arm 1.65, w ich is mounted upon one of the main stay bars 166 of the machine, said bracket 165 being held in the desired adjusted posi tion upon the stay bar 166 by means of a set bolt 167. This bracket arm 165 extends ..at a slight angle from the stay bar 166 and has its upper end formed with a curved recess or notch to engage freely the annular groove 155 of the double feed roller155, so as to retain the roller 155 in the desired position and at the same time permit it to rotate freely with the shaft 150. The bracket 165' is also formed with a fclrwardly projecting bearing lug 16.5 in. which is journaled the inner end of the adjusting screw 137, and by which said screw is supported in proper alinement for performing its work.

Arranged between the bracket arm 165 and the side frame of the machine is a vertically extending arm or plate 170 formed with an elongated interiorly bored and threaded hub portion 176, through which the adjusting screw 137 is threaded. The upper end of this arm 170 is recessed and shaped to fit partly around the sleeve por tion 157 of elongated roller 157 in the annular groove separating the two milled wheel portions 157 of said elongated roller. By this means the rotation of the adjusting screw will cause the arm 170 to travel laterally and move the elongated roller 157 upon its shaft 150.

Arranged between the arm 170 and the side frame of the machine is a series of lazy tong levers 175, and arranged between said arm 170 and the bracket 163, is another series of lazy tong levers 176. The outer end of the lazy tong levers is pivotally connected at 177 with a bracket plate or link 178 secured at179 to the inner face of the side frame of the machine. The opposite endof the lazy tong levers 175 is pivotally connected at 180 with a link 181 which is in turn pivotally connected at 182 to a flange or lug 183 projecting laterally from one face of the arm 170; whereas'the outer end of the lazy tong levers 176 is pivotally connected at 185 with a link 186, which is in turn pivotally connected at 187 with a flange or lug 188 formed integral with and projecting from the opposite face of the arm 170, and the extreme inner end of the lazy tong levers 176 is pivotally connected at 190 with a link 171, which is in turn pivotally connected at 192 with a lug or flange 193, formed integral with and projecting from the bracket arm 165.

Projecting upwardly from the central pivot of each pair of lazy tong levers 175 and 176 is a post or arm 195, such as shown in Fig. 13 of the drawings. These posts 195 are mounted upon the central pivot pins 196 of the lazy tong lovers, the levers being secured upon said pivot pins bynleans of nuts 197. Each of the posts 195 is formed with a rearwardly opening yoke 198 in its upper end which partially encircles the hub or reduced portion of one of the feed rollers 156 or in other words rests easily Withi he an%126 'parts referred to.

jcctionable use of removable set screws 1s and sheet transfer fingers 161, will be simultaneously and correspondingly adjusted. By a comparison of the positions of these last named parts as shown in Figs. 11 and 12, it will be observed that in one extreme position of adjustment, the under feed rollers and transfer fingers will be presented in close order adjacent to the center of the machine, whereas in the other position said parts will be presented in close order ad acent to the side of the machine.

In adjusting the operating parts of a feeding machine in accordance with my invention, it will be understood that the parts upon opposite sides of the machine are separately adjusted, but that it. is only necessary to operate a single crank at eaclrside of the machine to accomplish the desired result. When the parts have been adjusted to the desired positions, the adjusting screws will remain in exactly the position in which they are left without any possibility of being accidentally moved, so that there is no danger of the disarrangement of the adjustments from the vibrations of the machine or from other causes, since it is necessary to positively rotate the series of adjusting screws to effect a change in the positions of the By this means the obavoided, which is of great importance in machinery of this kind, since it obviates the reat difi iculty incident to the independent adjustment of many small parts, and also avoids the possibility of such removable screws becoming dislodged and falling into parts of the machine with resulting damages.
